To all whomit may concern:

Be'it known that 1, JOHN K. TURTON, a citizen of the United States, residing in Richmond Hill, borough otQueens, city of New York, State of New York, have invented certain new and useful Improvements in Wheel-Rims; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In the present heavyconstruction of automobile wheels having removable pneumatic, cushion or other similar elastic tires, much difliculty is met with whenever it becomes necessary to remove the tire from the wheel rim. .In order to secure the best attaching effects, the tire is constructed to hug the rim closely and, being set in a groove therein and of heavy and cumbersome. construction, it is a source of great trouble'and inconvenience'to. make the tire leave the groove of tlie rim and clear the-rims extreme periphery; in order to accomplish this, the tire must be expanded to the size of the rim measured by its maximum diameter. The same difficulty, to the same degree, is of course. met'with in replacing the tire on the a a The principal object of the invention herein shown and described is to provide a wheel in which this difiiculty may befully avoided, sothat the tire, when necessary, may be removed or replaced with the minimum of inconvenience and loss oftime; inciderr tally, my invention involves. a simplified, more substantial and durable connection between the various parts and particularly .between the rim and felly, which latter are moreover rendered readily and quickly. separable in themselves, in addition to several other features of: advantage, all of which will be I at once apparent to those skilled in the art on a view to this specification and the accompanying drawings, wherein similar letters indicate the same parts throughout, and wherein Y Figure 1 is a view in side elevation of so much of the improved wheel as shows the essential features thereof; Fig. 2 is a sectional view on line x-x of Fig. 1; Fig. 3 is a sectional view on line y-g of Fig. 1, the tire being removed; Fig. 4is a view like Fig. 1 with the tire and other parts removed; Fig. 5vis'a plan view of what is shown in Fig. 1,. with the tire ren1oved;.Fig. 6 is a side elevation of the rim; Fig. 7 is a sectional view on line 2 of Fig. 4; and, Fig 8 illus tratesa detail. i

The folly of the wheel is shown as comprising the folly proper or body part a, which may be of wood, and the steel band'or shoe Fwhich, being shrunk perfect fit between rim and felly, whereby to avoid onto the part a, binds the same and the spokes and hub of the wheel together into a rigid substantial structure not affected by vibration and similar injurious infiuences/ For a purpose hereinafter set forth, the band .b .is bent to form a transverse groove 0 in the tread of the folly, such band being received by a corresponding groove (1 formed in the periphery of part a; also, the folly is chamfered, as at e, at both sides of its tread, giving the same in the portion involved a wedge-like form.

f designates the rim, which is preferably formed by so collapsing and thereupon otherwise shaping a me.- tallic tube as to produce the laminar body part and two lateral hollow flanges h which curve upwardly and inwardly toward each other to produce the shoulders i and groovesj and which project downwardly below the plane of the body part 9 to form therewith the tread portion of the felly. In order to secure a lateral play and creeping-of the rim, the wedge portion of the latter (already described) is utilized by so forming the metal of the rim that the side walls l of the groove 10 are convergent (Fig. 3).

The rim is not continuous or unbroken, butis split, as shown in the drawings. Into each end of each hob low flange h thereof is fitted a plug or block mwhich may be brazed to the metalof the rim to make it substantially an integral and rigid part thereof. As, in practice, the ends of the rim, thus split, would stand somewhat distanced from each other, a continuous bearingfor the tire may be formed where a gap would otherwise exist by extending the upper lamina of the body part 9 of the rim at one side of the gap and the under lamina of the body part g at the other side of the gap, as at n and 0, respectively, and overlapping them;

they may be made to hug each other closely by turning the 'edge portions p of the former around those of'the latter, as shown in Figs. 2 and 7, whereby to avoid any chance of their pinching the inner tube, where the tire comprises such.

The blocks in are formed with alind tapped holes q and these receive the ends of rcversely threaded screws tr adapted for contracting or expanding the rim by causing them.to alter the distance between the ends of the rim at the split upon turning the screws. As a means for manipulating both screws at once, whereby to cause any change of diameter in one side of the rim to have its precise counterpart in the other, I provide the following arrangement: I

s is a spindle bound to the two screws 1* at right anglesthereto by slings t of U-shape in front elevation, in which said spindle may rotate but is prevented from longitudinal movement therein by shoulders nwhich engage the inner faces of said slings, The ends of the spindle are formed as worms 1), and engaging with each worm is a worm-wheel w which is pinned onto the corresponding screw r and keeps the sling which has a bearing on the screw both sides of the worm-wheel, from sidewise movement. Upon rotating the spindle the gearing described will rotate both screws simultaneously, so that a uniform adjustment is transmitted to the rim; such rotation may be affected upon applying a crank or wrench, such as .r. to one of the squared ends 3 of spindle s. The spindle s is received by the hereinbeiore described groove c of the telly.

The tire shown in the drawings is of the inner tube. pneumatic, so-caller'l clinch'er" type. comprising the open casing or tire proper having the laterally flanged or shouldered base portion 2. and the inner tube 3. It will be understood that when the tire is assembled with the rim and then inflated the flanges 2 will engage in the grooves j and under the shoulders i of the rim to in-v terlock the rim and flange.

As will be hereinafter shown. the operative condition of the tire. will be such that there is a grip produced as between tire and rim sufiicient to prevent creeping of the tire; but this effect may be augmented or otherwise produced by forming c -engaging corrugations 4 5 in the base 2 of the tire proper and in the rim, the same forming a substantial obstacle to creeping when, for instance upon inflating the tire, they are made to interlock.

In assembling the parts, the rini being removed from thefclly, the screws are turned by rotating the spindle in the proper direction to cause the screws to contract the split rim until its diameter is such that the tire may, he slipped over the rim without undue dii'ficulty The crank is then turned in the opposite direction until the screws cause the rim to expand sufficiently so as to just about clear the peripheral diameter of the telly, whereupon the rim is placed in surrounding disposition with relation to the telly and the crank again rotated in the reverse direction. thistimc to cause the rim to contract and thus receive in its groove the peripheral portion of the ielly. Having bound the rim to the telly under the proper tension, the tire (if ,it is of the pneumatic type) may be now inflated; or it may be already inflated when placed on the rim. It is preferable, of course, that the normal inside diameter of the tire. when inflated, be then at least no greater than the corrcspondiugor outer dimension of the rim so that the resultant grip of the tire on the rim will of itself act to materially prevent the former against creeping.

My invention, as will be now obvious. provides a wheel construction wherein the parts are not only capabio of assomblago and separation quickly and conven iently but are so formed as to cotiperate to produce great strength and durability and withstand the enormous wear and tear to which structurcs of this character are peculiarly liable. As it requires but. a short time to assemble or disassemble the parts. an automobile may carry with it an extra rim and tire fitted together, the tire fully inflated ready for quick application to any wheel upon its becoming unfit for service.

Having thus fully described my invention. what I claim as new and desire to secure by Letters Patent is:
